Abstract: PURPOSE:To improve the transfer rate of recording/reproducing by controlling the track-jumping of a light spot by a prescribed number in every prescribed number of rotating speeds of a disk in accordance with the detected output of a position detecting means. CONSTITUTION:Semiconductor lasers 10-12 as light sources emit a laser light and a light spot is projected on a disk D through a collimator lens 2, a beam splitter 3 and an objective lens 4. The output levels of the respective semiconductor lasers are changed over individually by means of a driving circuit 13. The circuit 13 switches the driving signal level supplying to the laser 10 according to the output data of a memory 7 and switches the driving signal level supplying to the laser 11 according to the output data of a memory 8. A position detecting means 14 detects the position of the objective lens 4 based on the returned light of the laser 10 from the disk D. A pulse signal oscillator circuit 15 generates a track-jumping signal in accordance with the detected output and a head is moved so as to be controlled. Consequently, the transfer rate of recording/reproducing is improved.

Title: Semiconductor device
Inventor: SAKURAI KEIJI
IPC: H01L29/861
Filed: 1993-11-17
Abstract: PURPOSE:To provide a rectifier element of a toward voltage drop much lower than a conventional one, by connecting a field effect transistor in parallel between a first electrode forming a schottoky barrier with a surface of a first conductivity type layer, and a second electrode to be connected to the other surface of the first conductivity type layer with a low resistance. CONSTITUTION:A MOSFET is connected in parallel through the medium of an N<+> layer 8 to a Schottky barrier rectifier element existing between an anode electrode 71 and a cathode electrode 72. As a result of this, the MOSFET turns on and current flows through the MOSFET, the n<+> layer, and a p<+> layer 1, if a positive voltage is applied to the gate terminal when a positive voltage is applied to the anode terminal A and a negative voltage to the cathode terminal K. That is because the current path is considered to be composed of all resistors, and because its resistance is lower than a path via a Schottky barrier formed between the anode electrode 71 and an n<-> layer 2. Forward characteristics at this time are improved compared with time when no voltage is applied to the gate terminal.

Abstract: PROBLEM TO BE SOLVED: To make molding with extremely good dimensional accuracy possible by disposing a hollow rubber mold into a metal mold enclosing a powder packing part, supplying a pressure medium into this rubber mold and molding the powder packed between the inside surface of the metal mold and the outside surface of the rubber mold. SOLUTION: After the powder 5 is packed into the inner side of a side frame 8 by removing an upper cap 11 of this CIP molding machine, this upper cap 11 is put thereon and a pin 13 is inserted into a pin hole 8b of the side frame 8 to fix and connect the side frame 8 and the upper cap 11. Oil is then forcibly fed into the hollow rubber mold 15 and pressure molding is executed by expanding the rubber mold 15. The oil pressure in the rubber mold 15 is released to shrink the rubber mold 15 to the original shape after the end of the molding. The pin 13 is removed, the upper cap 11 is removed and the molding is taken out by shifting side frame outward. As a result, the outside surface of the molding has the shape complying with the inside surfaces of the side frame 8 and the upper cap 11 and, therefore, its dimensional accuracy is good.  Even its inside surface is merely necessitated to be removed of the part in contact with the part near the bottom end of the rubber mold 15. A straight cylinder or rectangular parallelepiped shape is thus obtd.
